Alice Morgan is beautiful, extraordinarily intelligent and dangerous. She's introduced as a key witness in Luther's first investigation. Luther, however, quickly discovers she is not as innocent as she seems.
A celebrated child genius, Alice completed her PhD in astrophysics at the age of 18 and worked at a London university as a research fellow. She's spent her life feeling different, special and freakish. For Alice, human existence is insignificant and life is futile and senseless — which is why she felt compelled to murder her own mother and father.
Luther has never been able to convict Alice and they've subsequently formed a strange and uneasy friendship. In the sequel, balance has shifted and it's Alice who needs Luther's help and support.
